Seizures are seen with which anesthesia context and must be differentiated from Emergence Delirium?

• A. Ketamine administration
• B. Propofol administration
• C. Sevoflurane anesthesia
• D. Nitrous oxide use

Answer: (A)

Ketamine can be associated with seizure activity in the anesthesia setting because it increases cortical excitability and can produce a dissociative state that lowers the seizure threshold in susceptible individuals. While it has many beneficial effects, including analgesia and preservation of airway reflexes, there is a risk, albeit uncommon, of convulsive movements during induction or emergence, especially in patients with a history of seizures or metabolic disturbances or when used at higher doses. Emergence delirium, by contrast, is a non-ictal, dissociative delirium that presents as agitation, disorientation, and inconsolable restlessness as the patient wakes, without the stereotyped convulsive activity that characterizes a seizure. Distinguishing features include the presence of rhythmic convulsions, tongue biting, incontinence, or a clear postictal return to baseline, which point toward a seizure rather than emergence delirium. Management differs accordingly, with seizures treated as such (often with benzodiazepines and addressing triggers), while emergence delirium is managed with safety, reassurance, and, if needed, light sedation. Propofol tends to have anticonvulsant properties and is less likely to provoke seizures; sevoflurane is more commonly linked to emergence delirium in children, though rare epileptiform activity can be reported.
